You can see which weasels I went with, those by Splintered Light, sculpted by Bob Olley, but I thought I may as well round up what options you have in case you're in the market and want to consider your options. Essentially, Otherworld and Reaper make some, and there's one for the D&D Minis game in the Aberrations set.
The prepaint figure is wrapped around a stalagmite and therefore a group of them would look like crap. And then there's that unfortunately decision Wizards made back in 3ed to give dire creatures a more evil back story and have spikes and crap sticking out of the skin of all the dire creatures. So the weird spikes would need to be shaved off and smoothed over.
Reaper makes both a "weasel" and a "ferret" and they sell them in variety packs of familiars. Thankfully, if you want a group of just the weasel or ferret you can get them from Hoard O Bits, who hopefully won't mind me nicking their pics in exchange for links back to the shop. These figures are much larger than a 25mm "normal" ferret or weasel would be, but are not quite big enough to warrant the "giant" appellation in 25mm.
The Splintered Light ones, meanwhile, have all the right attributes:
- Good sculpting
- More than one pose, and poses that look good in a group
- Won't break the bank
- Perfect size for 25mm or 28mm (despite being sold as 15/18mm)
I also hugely appreciate that either Splintered Light or Bob Olley had the foresight to a) makes the bases of these large enough that I don't have to base them but no so large as I have to have cut them off and b) add a little texture detail to the base. That's so much time saved.
